HISTORY OF EBOLA
Ebola virus first emerged in 1976 in outbreaks of Ebola hemorrhagic fever in Zaire and Sudan . The strain of Ebola that broke out in Zaire has one of the highest case fatality rates of any human virus, roughly 90%. The name of the disease originated from one of those first recorded outbreaks in 1976 in Yambuku , Democratic Republic of the Congo (then Zaire) which lies on the Ebola River . The Philippines and the United States had no previous cases of infection, and upon further isolation it was concluded to be another strain of Ebola or a new filovirus of Asian origin, and named Reston ebolavirus (REBOV) after the location of the incident. Some scientists also believe that the Plague of Athens , which wiped out about a third of its inhabitants during the Peloponnesian War , may have been caused by Ebola. However, these studies are conflicting, and point to other possible diseases such as typhoid.
